Adaptive control simulation of underwater vehicle ballistic

The ballistic of underwater vehicle is one of the key technologies of the submarine-launched tactical weapons which launch success or failure, and has a strong nonlinearity, the fast degeneration as well as the characteristics of strong coupling. In order to facilitate the research questions, this paper proposed a class of nonlinear adaptive control algorithm for the longitudinal ballistic of underwater vehicle, which pitch angle changes in a wide range. Firstly, 6 DOF motion mathematical model is established precisely for underwater vehicle considering the existence of the current disturbance; Secondly, the online adaptive method is used to solve the nonlinear problem of longitudinal ballistic model, and design adaptive control law; Finally, based on the 6 DOF underwater vehicle ballistic model and nonlinear adaptive control algorithm, the longitudinal ballistic of the vehicle is tracked and the validity and rationality of the controller is verified.
